Hey, everyone. Let's take a look at this question together. What is the term used to describe all of an individual's DNA? Is it answer choice? A chromosome answer choice B nucleotide, answer choice C genome or answer choice D gene pool. Let's work this problem out together to try to figure out which of the following answer choices is the term that is used to describe all of an individual's DNA. So in order to solve this question, we have to recall what we have learned about the following terms to determine which is that term that is used to describe all of an individual's DNA. And we can recall that all of an organism's genetic material, which includes its genes and the non coding sequences of DNA is referred to as the genome. Since the genome encompasses the entire set of instructions needed to build and maintain an organism. And within humans, it's organized into 23 pairs of chromosomes including the sex chromosomes. So since the term that is used to describe all of an individual's DNA is the genome answer. Choice C genome is the correct answer. And all other answer choices are incorrect, I hope you found this video to be helpful. Thank you and goodbye.
